Save results to a text file in PHP

First of all I want you to know that my knowledge about coding is very very low, almost 0. I have done some coding using tutorials, but now I am stuck :(

I have this code:

$fp = fopen('myfile.txt', 'w');
fwrite($fp, "Kilometrii : $a. Consum : $b. Pret : $c.Cost : $num4.\"); 
fclose($fp);

This code is doing some calculation and then it saves the results to a text file. My problem is that it saves only one result; if I do a second calculation it overwrites the first result and so on. My second problem is that the result is saved on a single line.

Example:

(Kilometrii : -88687. Consum : -148.06115890717. Pret : 0.00024164007585046.Cost : 31.73.\ ).

I want to show the results one above the other and separate multiple calculations by a bigger space. Please help me! Thank you!

You need to append with a and you have an errant backslash \, but you can use it to add a newline \n:

$fp = fopen('myfile.txt', 'a');
fwrite($fp, "Kilometrii : $a. Consum : $b. Pret : $c.Cost : $num4.\n"); 
fclose($fp);

If viewing in a browser you'll need a <br> instead or run it through nl2br().

You are opening the with the w flag which truncates the file to zero length. You probably want to open it with a (append mode) to not erase the file and put the cursor at the end of the file. You can see all the modes on the fopen manual page

Example:

$fp = fopen('myfile.txt', 'a');
fwrite($fp, "Kilometrii : $a. Consum : $b. Pret : $c.Cost : $num4.\n"); 
fclose($fp);

Try this, fopen('myfile.txt', 'a') instead of 'w'. Including a link for further reference http://php.net/manual/en/function.fopen.php
